T 0 all 'whom t may conccm: Be it known that l, FRANK HENRY Anson,

`a citizen ofthe UnitedStates of America,l

and resident of Iroquois Falls, Province of Ontario, certain new andMachines for Applying Heads to the Ends of Rolls, and do hereby declarethe-following to be a full, lear, and exact .description of the same.

This invention relates to the mechanical application of paper discs' orheads to theends of rolls of paper and appertainsv p'ari release theroll to permit its removal with the heads applied. y

ln so far as, I am aware machines of the above mentioned type tokmanually operatedv headers of limited capacity withrespect of the'lengthof rolls to be accommodated with the result the use o-f the machine hasvbeen limited and, its operation necessitated practically constantattention uponthe part of the operative in ensuring` that the necessarysteps beA taken for lthe application of the heads and release vo1theroll at the proper periods.

An object of my invention is to avoid shis ,deficiency by the provisionthroughout the Wliolef`range usually encountered andl to provide for,power op,- erated brackets:preferably` under automatic control whereby,subsequent tothe applica- V tion of the heads to the roll, and at a pre`determined pressure such brackets are relieved of pressure andsubsequently i'eleased to permit of its removal, thus simplifying theoperation and', in addition to mak- .siniplifying Iits oiperation'withresultant increase in capacity. y y n Heretofore the supporting bed ofthe platform. upon which the paper roll was su ported been made'stationary with tne Dominion of Canada, have invented ,i usefulImprovements in the paper heads toV have been confined Fig. 2.,

of a machine lengths ofv roll` ing the machine more universalin vitsutility,

result that should the roll move longitudi-y nally under the pressure ofthe movable brackets, the roll itselfA or its outside wrapper wouldscrape along the platform and-be torn, especially vin the case of largerolls which ,are of considerable weight and a further object thereforeofv this'inventionis to avoid the possibilityfof such damage by Atheprovision of an antifriction bed or supporting portion vwhich willfacilitate move- Vment of the roll and thus prevent scraping of thelatter.

A still further in proper alignment with the roll irrespective of theAdiameter .of the flatter, this featuse, inv conjunction with theconstruction providing kfor the accommodation of a` wide range of rollthoroughlyy flexible and universally. adaptable machine vthan hasappeared heretofore.

The above with further objects and advantages ywill be hereinafter morefully delengths, providing lfor a. more object of the' invention coni-Vsists in the provision of adjustable supportsy for the heads carriedby the applyingv brackets so that said heads can be adjusted my inven-vscribed and particularly pointed out in the ,e

appended claims. e .e

For full comprehension, however, of my invention reference should be hadto the accompanying drawings forming a part of this specification, inWhichthe same reference characters indicate like` parts and wherein Y fFig. l is a longitudinal section of my improved kroll press and headapplying machine, the section Fig. 2 is a plan view' of the machine;Fig. 3 isa cross-section on line 3-3 Fig. 3; and l control.' A

y Referring now to `the drawings, the bed of the platform Aforsupporting the'rolls to be headed, consists of a seriesv of rollers 9.,horizontally disposed in yparallel relation and supported at theiropposite ends by trunnions 3 bearingv in Z-bars 4 extendinglongitudinally of t-he machine and supported by vcto-extending Fig. l isa Wiring diagram of the motorvw I-beains 5 suitably mounted upon thefoundation of the machine.

These rollers are individually rotatable and i constitute `ant-ifrictionelements of the plat-` form upon'which the paper rolls which are to beheaded are` placed, the rolls extending `outer; side ol'fthe platebeingcprovided with transversely of the rollers and the centreportionsvoi' the latter being concared or reduced to provide adepression ior the reception ot' rolls to prevent accidental movementoil the platform.

Upright brackets aresupported upon the Each ot. the` brackets preferablyconsistsota -tiat plate 6. arranged transversely across the platformperpen-dicul v thereto, the

braces-8 at either side `and eitendingv do wardly on the outer sides otthe '-.beai thewheels being mounted upon the lower endsof these braces.`The plate G oi `cach bracket. is backed by a casting 9 p` I top andbottom anges l0 and a .ce largement recessedy atll the. frontendcommunicatingwith Va vertical slot l2 in plate 6. bloc-lr 13 mountedtherein for verticamovement7 such movement beingrimparted theretoby yavertical-shaft l--.in screw-threaded engagement with theebloclrandextending upwardlytherefrom loosely through the enlargement and in screwthreaded engagement withy top` flange l0 above which the shaft is ittedwith a hand wheel 10a.l llaeh block carries a pin l2 which entendshorizontally outwardlytherefrom through slot l2 in the plate. 6 and ybyrotatingbT lthe shaltV through t-hewrnedium otihandfwheel iGa'thc blocl;l5 is causedv to move up,v or down and through it the level of .the pinis raised or lowered with respect to the platform. rlhe pins l2 areutilized to support a supply o head,- or paper discs ready torapplication tc the paper roll and to enter the a l hole ot the roll whenthe brackets are moved inwai to-apply the heads and the adjustment l'described enables the pins to beaccu moved vertically into exacthorizontal at ment with a roll irrespective ot theA diameter of thelatter, thel slot l2 and recess il bei designed 'for the accommodationoi" the dii.- ierent.diameters ot' rolls likely telic encountered.

Power apparatus is provided tor moving thefbraclet-s longitudinally overthe glatorm and `nhile any suitable apparatus may be employed, onearrangement which'is pecially suitable for the aurpose will nowbedescribed.

This power drive consists ot 'an electric motor l5 operatively connectedto spindle boltsV 16 by -means ctv-.nich the brackets are movedl Asshownin the drawing the Eaclrrecess ll accommodates a.

motor is supported transversely at one end oi the platform, theoppositeends ot the motor shaft l? having worms 18 mounted thereon and meshing`with worm `sears carried by spindle bolts 16 one o' which latter isarranged on the outside ot each beam 5. These spindle be extent.throughtlie -ength ot' the platt rm and are each rotatably supported atthe center by a bearin@` 19 at the motor enf by bcmings 220, and at theopposite end by a bearing 2l. The

spindle bolts are respectively formed with right and letti hand threadsopposite sides or the central bearingsain. a 'e in en.- gagement withnuts. 29 carried ny each ot the brackets so that when driven by themotorthese spindles cause Vthe bra -liets to move inwardly towards each otheror outwardly away from each other over the platform in acc relance withthe direction ot rotation ot the motor.

ln the operation et the machine with the ln'aclets spaced apart asillustrated and the pins siuinortinsa)` asupply ot heads the outermostheads-are coated with adhesivemateri anda roll indicated at 241 is movedupon the platform between the braclets7 the pins being then adgustedinto alignment with the axial line ot the roll.' rlhe motor is tienstarted inthe forward direction to move the brackets inwardly towardsthe roll thus pressingy the outermost heads against the ends ot theIroll to which the heads adhere. It the pressure upon the roll at thistime causes it to move longitudinally such movement is accommodated bythe rollers 2 and tearingv ot the roll or otits w upper .is prevented.lli/Then sutticient pressure has been applied the motor is automaticallystopped and then driven in reverse directionl to withdraw the bracketsthus treeino' the roll and permittinggit to be .removed from theplatform.

The operation of motorn 15' is controlled by a conveniently locatedVfloor switch operating as shown -by diagram in Ll wherein 25. is a pushbutton switchV for torward operation ot the motor, 26 a push buttonswitch for reverse operation oi the motor, 2T a push button switch forstopping vthe motor, 28 a limit switch7 29 a double pole relay, 30, 30na reversing panel consistingoi two 2 pole contactors and 31a vgravityreset current operated relay with adjustable calibration. When startingswitch closed a circuit is umile from contact ik et line switch toContact 33 through operat coil ot' double pole relay 29 and coil to thestarting switch by wire 35 and bach to contact 40 of line switch throughwire 3G, This circuit closes cont-acts of relay 29J short circuiting theoperating coils ot' current operated relay 31 so that the latter willnot operate on the start and keeping contacts 3?' and 38 closed. Themotor circuit follows from ficy ` contact A32 topcontact 33jof yrelay 29through `described through the limit switch lead 32 to coiitactBS andback to contacty 38 on Vthe current operatedy relay 3l through contact37 to-aiid through the operating coil of pole contactor` BOGto contactl`39 of` forward starting switch 25 and back to contact 40 of line switchby wire 36, thus pulling in all 3 contacts of contactor starting vmotorin forward direction.

Switch 25 is lield closeduntil motorg'aiiis speed, the heavy startingcurrent at this time being short` circuited and not passing through thecoils of current operated relay 3l, the contacts 37 and 38 of the latter,remaining closed. When the motor has gained speed the current dropsdown to nor-v mal. The switch 25 is then released by the operator andallows the relay'29 to open up its main contacts forcing the current intwo legs of the motor'circuit to pass through the coils'of relayl.v Atthis time contactor 30 does not dropout since lthe auxiliary contact 4lon coiitactor Ofst-illr maintains a circuit throughl the operating coilby way of auxiliary contact 41, wire 42, reverse switch 26, wires 43 and36 to contact 10.

The forwardly operating motor moves-the brackets against theroll and thepressure increases'and with itthe pressureof the current increases untilthe latter reaches a predetermined pressure operated relay 31 has beenadjusted `and at this time the contacts 37 and 38 are caused to openthus breaking the circuit through the operating coil of contact-or 80,

opening the contactsv thereof and 'automatically` stopping the motor.When the motor stops all relays'are restored'to -normal condition. 'i

To withdraw the brackets from the `roll they switch 26 is closed toreverse the operation of the motor, the closing of the reversev versedirection a distance limited by the opening of .the limit switch by thelengagement therewith of a stop carried by the bracket, this stopengaging .the button on the limit switch at 47, causing the contacts 87,38 to open thus breaking the 'circuit Y' through the operating coil ofcontactor 30a,

opening contacts thereof and automatically stopping the motor. t- Themotor being stop- 30 and :p

From the above it will be'seen that I have rolls varyii'ig both in andof operating upon same without likelihood of damage theretoand a'machine iny which the rolls can be handled in afquick and efficientmanner. Furthermore the operation of a machine constructed according tothe above simplifies the operation to be performed'and the automaticstopping of the power-driven brackets at a certain predeterminedpressure precludes the possibthe machine due to the application ofexcessive pressure,Y That I claim isfas follows:
